1725, "the need very badly to urinate," from L. micturitum,
from pp. of micturire
"to desire to urinate," desiderative of mingere
"to urinate," related to meiere
(n.)). As during the final 20 minutes of a 4-hour film after drinking a 32-ounce Mountain Dew from the snack bar and the movie ends with a drawn-out farewell scene while Frodo is standing on the pier and wavelets lap audibly on the dock as if the director was a sadist set on compounding your torment.
